Integral sealing type electrical heat tracing anti-explosion material filling head

Abstract

An integral sealing type electrical heat tracing anti-explosion material filling head comprises a sealing jacket integral electrical heat tracing material filling rod, a valve element, a three-way body, a sealing assembly and a sensor and is characterized in that the sealing jacket integral electrical heat tracing material filling rod comprises a heat conducting belt, an electrical heat tracing belt, an upper pressing plate, a lower protective sleeve, an outer protective sleeve and an inner protective sleeve, wherein the electric heat tracing belt penetrates through a groove of the lower protective sleeve, and the heat conducting belt is wound on the outer wall of the inner protective sleeve. The integral sealing type electrical heat tracing anti-explosion material filling head has the advantages that according to material characteristics and the operation temperature requirement during filling, real-time heating is achieved through adjustment with a central control system; through cooperation among the inner protective sleeve, the outer protective sleeve, the heat conducting belt, the electrical heat tracing belt, a fixing belt and an outer heat insulating belt, the effect of heat insulation and the effect of insulating anti-creeping protection are realized while the electrical heat tracing function is realized.

Description

technical field [0001] The invention is suitable for the filling industry of chemical liquid materials, and is especially suitable for filling liquid materials with high operating temperature and easy condensation. Background technique [0002] With the continuous advancement of science and technology, there are more and more varieties of chemical materials, and the differences in their material properties are also increasing. Different materials have different requirements on the operating temperature during filling. [0003] In the current chemical filling industry, in order to solve the problem of different materials and different operating temperatures during filling, the charging gun can be roughly divided into the following three types of electric heat tracing: [0004] Filling gun origin heating type: It is characterized by a simple structure of the filling gun and a long filling rod, which is suitable for filling under the liquid surface; its disadvantages are: 1.

Problems solved by technology

[0004] Filling gun origin heating type: It is characterized by a simple structure of the filling gun and a long filling rod, which is suitable for filling under the liquid surface; its disadvantages are: 1. The filling gun cannot be heated in real time, and the temperature difference changes greatly, which may easily cause the material to reach If the temperature is lower than the operating temperature, the viscosity will increase, and the charging gun will be blocked; 2. The origin heating of the charging gun uses an open heating device, the heating time of the charging gun is long, the energy loss is large, and the mechanism is complicated

[0005] Half-jacketed electric heat tracing charging head plus origin heating: it is improved on the basis of the origin heating of the charging gun. The real-time heat tracing of the upper part; its disadvantages are: 1. The electric heat tracing device is a non-sealed mechanism, which can only trace heat for the nitrogen-filled rod that does not contact the par
